My roster is humble. You may find it here: Help me to build a defense team, please
Ive got Khiona when she was the hotm. Lot of time ago and never was really successful in using her. Had her with 20 emblems a while ago but ended splitting them for Domitia and Zocc. Other 1200 Emblems are on C. Marja.
I lack good purples and I like using Khiona between Mokkar and Quintus for the great attack buff and healing… But … c. Rigard does both better than her + cleanse 
Now with family bonuses I think she should do better specially with Drake. I could reset Domitia and use the spare emblems on her if she ends up working good… Who knows
She has none now for lack of use. She were +20 on ATK path.
Thank you for the conversation. I can’t find many Khiona owners to talk about it <3
